Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
गच्छत्यसावनुदिनं परिवृत्य रश्मीन् देवान्पितॄंश्च मनुजांश्च सुतर्पयन्वै शुक्ले च कृष्णे तदहःक्रमेण कालक्षये चैव सुराः पिबन्ति //
gacchatyasāvanudinaṃ parivṛtya raśmīn devānpitṝṃśca manujāṃśca sutarpayanvai śukle ca kṛṣṇe tadahaḥkrameṇa kālakṣaye caiva surāḥ pibanti //
He (the Sun) moves onward day after day, turning back and spreading his rays, truly satisfying the gods, the ancestors (Pitṛs), and humankind. In the bright fortnight and in the dark fortnight, in that very sequence of days, and at the waning of time as well, the gods drink their share.
It points to a cyclical vision of time governed by the Sun, including “kāla-kṣaya” (the waning/consummation of time), implying that even cosmic decline follows an ordered rhythm rather than chaos.
By emphasizing pakṣa (fortnight) and day-sequence, it supports dharmic time-discipline—performing daily rites and timely offerings to Devas and Pitṛs (e.g., homa, śrāddha) so society remains ‘sustained’ in the proper order.
Ritually, it stresses that offerings and observances depend on correct calendrical timing (bright/dark fortnight and day order). This timing principle underlies temple ritual schedules and consecration/observance calendars used alongside Matsya Purana–style dharma and vidhi.
